FOREWORD This report provides the rationale for and contents of a videotape created for institutional Bradley Fighting Vehicle gunnery training. The project is part of an overall mission to assess instructional strategies and technologies to improve weapon system training. Sponsorship for Bradley research has been provided under a 1983 Memorandum of Understanding between the Training Technology Agency at TRADOC, the U.S. Army Infantry School, and the U.S. Army Research Institute for the Behavioral and Social Sciences (ARI). The videotape was designed to be used as intrcductory material for students receiving Bradley training before handson instruction on the Conduct of Fire Trainer (COFT). The COFT is a computer-driven high fidelity precision gunnery training device used in Bradley units worldwide. The importance of the device, the computer-generated graphics, and the unique scoring system justify development of standardized pretraining materials. The videotape was developed in close coordination with Bradley COFT instructor/operators and trainers and has been provided to the 29th Infantry Regiment, Bradley Instructor Detachment, for use in institutional training.

BRADLEY UNIT CONDUCT OF FIRE TRAINER INSTRUCTOR/OPERATOR PROCEDURES: A VIDEOTAPE INTRODUCTION The Conduct of Fire Trainer, the COFT, is a sophisticated training device. It is a computer driven, high fidelity precision gunnery trainer developed for the Army by General Electric's Simulation and Control Systems Department. The COFT is available for the M1 and M60A3 series tanks and for the M2/M3 Bradley Fighting Vehicle (BFV). The Unit Conduct of Fire Trainer (U-COFT) is found in units world-wide. It provides basic gunnery skill training for novices or transition and cross training for personnel with some related prior experience. The U-COFT is primarily used as a home station sustainment trainer. It is used for diagnostics or to ensure that a crew has achieved minimum proficiency before live fire. It can be used in preparation for a gunnery density or to complement other training to insure that gunnery skills do not deteriorate through lack of practice. In addition to the U-COFT, there are two other versions of the COFT. The Mobile Conduct of Fire Trainer (M-COFT) is used by National Guard units. It is a self-contained U-COFT housed in a trailer. When transported, the M-COFT becomes a mobile gunnery training center. The Institutional Conduct of Fire Trainer (I-COFT) is used for gunnery training at the Armor and Infantry Schools. It has tutorial and practice exercises for the novice, and provides a self-paced program of instruction (POI) for basic gunnery. Specific skills are taught by the device and a trained instructor/operator (10). The I-COFT is used primarily for basic or transition training, although it can be used in a U-COFT mode for experienced crews. Although the I-COFT is similar to the U-COFT in many aspects, there are certain major differences. These vary from the method of instruction to differences in the physical layout of the trainer itself and procedures to be followed in placing the trainer in operation. Physical Description of the U-COFT The U-COFT is a stand alone shelter for individual crew gunnery training. It has several furctionally distinct components. One section contains computers that provide exercise scenarios and store and manage data. A briefing area provides remote monitors so crews awaiting training can watch others fire. An individual crew station replicates the commander and gunner's positions, and with a very few exceptions, is identical in appearance and function to the BFV turret. The 10 sits at an instructor/operator station (the IOS or 10 station) to
conduct training. The IOS has two color monitors which replicate what the commander and gunner see in their sights and a situation monitor which indicates upcoming targets and locations. A keyboard and terminal printer enable access to the system and data entry. Physical Description of the I-COFT The I-COFT is a set of four unsheltered U-COFTs linked together. I-COFTs are housed inside of buildings especially configured to maximize I-COFT training efficiency. The four I-COFT crew stations and 10 stations can be separated from each other by curtains; a large computer area is located at each end of the training area. The I-COFT has no remote viewing area; _ students monitoring I-COFT training watch the IO's monitors, and listen through headsets attached to his console. A crew command input device (CCID) driver control panel simulates limited driving activity. Additionally, student help and student response buttons are located in the turret to facilitate basic gunnery training. The I-COFT, unlike the U-COFT, has a voice generating system (VGS) which permits the computer to serve as synthetic commander in some POIs. Although each I-COFT can operate independently of the other three, there are mechanisms by which two or more I-COFTs can be connected. Critical Differences Between U-COFTs and I-COFTs Because of the variance in physical construction between the two systems, some of the major differences between the U-COFT and I-COFT impact on the 10 and the procedures he follows during daily operations. For example, there are critical procedural differences in the before-operation preconditioning checks. The U-COFT's three major sections are connected by air bags which insure the integrity of the climate controlled system. Each day the 10 must check the externally located U-COFT air bags to insure that they are intact and without damage. He must also insure that the five air conditioning units located in each U- COFT are in operation. Each individual air conditioner must be checked for temperature setting, function, air flow, and water level. None of these procedures is necessary in the I-COFT since it is housed inside of a climate controlled building with central air conditioning. In readying the U-COFT for daily training, the 10 must check to insure that shelter lightning rods are in place, that exterior power cables are connected, etc. Before training he must insure all four of the shelter doors are unlocked to provide access and emergency exit. These procedures are not necessary in the I-COFT. Power up and power down procedures differ, as do the procedures to be followed in recovery training capability after a catastrophic power failure. 2
The Problem The Bradley Instructor Detachment (BID) at Fort Benning, the primary trainer for BFV personnel, not only trains students to be gunners and commanders, but through the COFT Branch, trains COFT IOs and senior instructor operators (SIOs). The 10 operates and maintains the COFT, and provides training for his unit. The SIO is responsible for a unit's overall COFT program, and for the training and monitoring of other los. Initial IO training is provided by a 46 hour exportable package at Fort Benning, in units, or as a part of a unit's new equipment training (NET). Master gunner students, already 10 qualified, receive SIO training as a part of their POI. In the past, 10 and SIO training were provided at Fort Benning using both the I-COFT and U-COFT. In 1988, however, the 29th Infantry Regiment, of which the BID and COFT Branch are a part, moved to a new location. The U-COFTs are no longer available, as all institutional COFT training has been transferred to 24 I-COFT stations. Gunnery training is unaffected because the I-COFT can be used in a U-COFT mode. However, loss of the U-COFT impacts on the ability to provide adequate 10 and SIO training. Since 10 students who train on the I-COFT at Fort Benning will be using the U-COFT to train gunners when they return to their units, they need to become familiar with U-COFT-specific procedures. The physical differences between the two trainers, the procedural changes and the unavailability of the U-COFT have made some documentation of these differences necessary. Accordingly, the COFT Branch requested that the Army Research Institute (ARI) create a videotape highlighting U-COFT procedures for 10 and SIO students who receive their training on I-COFTs. Newly certified IOs and SIOs returning to their units and U-COFTs can then practice and be tested on the actual procedures with which they were only familiarized during their institutional training. PROCEDURE A preliminary videotape outline was written, based on the correct U-COFT procedures as detailed in the U-COFT Operator's Manual, TM 9-6920-737-10 (Department of the Army, 1985, 1987). (See Appendix A for the procedures.) Over the course of a week, ARI and BID COFT personnel used two video cameras to film specific U-COFT procedures both outside and within one of the old U-COFT shelters. Taping was done with COFT IOs performing the correct procedures and another 10 monitored all filming to insure correct sequences. Filming was done on a real time basis, although the final tape was slightly edited. Based on the 3
outline, a narration was written to go along with the visual scenes. (See Appendix B for the actual script.) RESULTS AND DISCUSSION The finished product, "U-COFT Procedures" consists of three short videotape segments: "Preconditioning Checks", "Power Up/Power Down" and "Recovery from Catastrophic Power Failure." The films have been provided to the Bradley COFT Branch for use in 10 and SIO training. They provide a short, systematic and standardized introduction to some U-COFT procedures in the absence of the actual device. Intended to supplement the existing written I-COFT training materials, the tape was designed in segments with three natural stopping points for teaching specific techniques according to their place in the POI. The narration describes the visually pictured computer shelter, the crew briefing/monitoring area, and the instructor operator station, delineating operator functions and daily procedures. Exterior shots walk the viewer around the outside of a U-COFT shelter, with the narration describing the IO's behavior as he performs each of the required daily checks before entering the shelter. Interior shots of the U-COFT show the locations and servicing of the air conditioners, and show the equipment which the 10 must operate. The computer area and switches are shown in detail, along with the procedures for putting them into operation or shutting them down. In sum, the film documents the 10 procedures which are required in the U-COFT but absent from the I-COFT. CONCLUSIONS Although a videotape cannot substitute for hands on experience with the U-COFT, and IOs must be thcroughly checked out on U-COFT procedures when they return to their units, the tape serves a useful purpose within Bradley training. First, it enables the institution to make use of a no longer available resource, the U-COFT. Second, it provides a standardized familiarization lesson to prepare novice IOs for what to expect when they arrive at their units and are ready to work with the U-COFT. The videotape presentation medium reduces potential errors, the quality of instruction is maintained, and BFV IOs will be better prepared to use their most valuable gunnery device, the Conduct of Fire Trainer. 4
